 ## 🔥 Latest Updates : 
+### August 6 2025: WanGP v7.7 - Picky, picky
+
+This release comes with two new models :
+- Qwen Image: a Commercial grade Image generator capable to inject full sentences in the generated Image while still offering incredible visuals
+- Wan 2.2 TextImage to Video 5B: the last Wan 2.2 needed if you want to complete your Wan 2.2 collection (loras for this folder can be stored in "\loras\5B"     )
+
+There is catch though, they are very picky if you want to get good generations: first they both need lots of steps (50 ?) to show what they have to offer. Then for Qwen Image I had to hardcode the supported resolutions, because if you try anything else, you will get garbage. Likiwise Wan 2.2 5B will remind you of Wan 1.0 if you don't ask for at least  720p. 
+
+Please note that the VAE decoding of Wan 2.2 TextImage is not tiled yet and it may produce VRAM consumption peaks (this doens't mix well with the 720p requirement).
+
+
 ### August 4 2025: WanGP v7.6 - Remuxed
 
 With this new version you won't have any excuse if there is no sound in your video.

+
+    e.g. [llava-hf/llava-9b](https://huggingface.co/llava-hf/llava-9b)
+

+        text_config (`Union[AutoConfig, dict]`, *optional*, defaults to `LlamaConfig`):

+        image_token_index (`int`, *optional*, defaults to 32000):

+        attention_mask (`torch.Tensor` of shape `(batch_size, sequence_length)`, *optional*):
+            Mask to avoid performing attention on padding token indices. Mask values selected in `[0, 1]`:

+            [`PreTrainedTokenizer.__call__`] for details.
+
+            If `past_key_values` is used, optionally only the last `decoder_input_ids` have to be input (see
+            `past_key_values`).
+
+            If you want to change padding behavior, you should read [`modeling_opt._prepare_decoder_attention_mask`]

+            blocks) that can be used (see `past_key_values` input) to speed up sequential decoding.
+
+            If `past_key_values` are used, the user can optionally input only the last `decoder_input_ids` (those that
+            don't have their past key value states given to this model) of shape `(batch_size, 1)` instead of all

+        inputs_embeds (`torch.FloatTensor` of shape `(batch_size, sequence_length, hidden_size)`, *optional*):
+            Optionally, instead of passing `input_ids` you can choose to directly pass an embedded representation. This
+            is useful if you want more control over how to convert `input_ids` indices into associated vectors than the

+        vision_feature_layer (`Union[int, List[int]], *optional*, defaults to -2`):

+            The feature selection strategy used to select the vision feature from the vision backbone.
+            Can be one of `"default"` or `"full"`.
+        use_cache (`bool`, *optional*):
+            If set to `True`, `past_key_values` key value states are returned and can be used to speed up decoding (see
+            `past_key_values`).

+            Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors for

+            Whether or not to return a [`~utils.ModelOutput`] instead of a plain tuple.
+        cache_position (`torch.LongTensor` of shape `(sequence_length)`, *optional*):
+            Indices depicting the position of the input sequence tokens in the sequence. Contrarily to `position_ids`,
